In chapter 215 Zeldris is going after the real Gowther, and doll Gowther is going with the real Gowther when they run.
We know that the real Gowther died.
The question is how did Gowther get away from Zeldris? Wasn't he important enough for Zeldris to capture? Or did the real Gowther sacrifice himself somehow?
What did you think happened?
